The UK Prime Minister, Cabinet and executive: the roles and powers of the Prime Minister, the prerogative powers, the Cabinet and collective responsibility, the factors shaping prime ministerial power, and the debate over prime ministerial versus cabinet government.

What this dot point is asking

You need to explain the roles and powers of the Prime Minister, the prerogative powers, the Cabinet and collective responsibility, the factors that strengthen or weaken a Prime Minister, and the debate over prime ministerial versus cabinet government. The CCEA AS 2 paper rewards precise knowledge of how the core executive works and a balanced judgement on where power lies.

The roles and powers of the Prime Minister

The Prime Minister's main powers are:

• Patronage. Appointing, promoting and dismissing ministers (and influencing other appointments and honours), which gives huge leverage over the governing party.
• Chairing and directing the Cabinet. Setting the agenda, controlling Cabinet committees, summing up decisions, and steering overall strategy.
• Leadership of the executive. Directing the machinery of government, supported by the Cabinet Office and Number 10.
• National and international leadership. Acting as the chief public face of the government and representing the UK in foreign affairs and diplomacy.

The prerogative powers

Prerogative powers are significant because they let the executive act without specific statutory authority and historically without a Commons vote, though conventions have developed (for example, a Commons vote before major military action) and some prerogatives have been placed on a statutory footing. They are a major reason the UK executive is powerful relative to the legislature.

The Cabinet and collective responsibility

In practice much decision-making has moved away from full Cabinet meetings to Cabinet committees, bilateral meetings between the PM and individual ministers, and the Number 10 centre, which is part of the case that Cabinet government has weakened. Collective responsibility is still enforced (ministers who cannot support policy are expected to resign), but it can break down at moments of crisis, and it has occasionally been suspended (for example during the EU referendums).

Factors shaping prime ministerial power

A Prime Minister's real power is not fixed; it varies with several factors:

• Size of the Commons majority. A large majority frees the PM from backbench pressure; a small or no majority constrains them sharply.
• Party unity and standing. A united party and a popular leader give authority; division and unpopularity erode it, and the party can ultimately remove the leader.
• Personality and skill. Communication, management of colleagues and political judgement matter greatly.
• Strength of senior colleagues. Powerful rivals in Cabinet limit the PM; weak colleagues enhance dominance.
• Events. Crises, the economy and scandals can rapidly make or break a Prime Minister.

Prime ministerial versus cabinet government

The central debate is whether power has shifted from collective cabinet government towards prime ministerial (or even presidential) government:

• The case for prime ministerial dominance. Patronage, control of the agenda, the growth of the Number 10 centre and the Cabinet Office, intense media focus on the leader, and the sidelining of full Cabinet all concentrate power in the Prime Minister.
• The case that constraints remain. The Prime Minister depends on Cabinet and party support, must manage rivals and factions, can be removed by their own party, and can be undone by a small majority, events or loss of authority.

The balanced judgement is that the Prime Minister is normally dominant but remains fundamentally dependent on colleagues and circumstances, so the system is best described as prime ministerial in normal times but capable of reverting to a more collective or constrained model when a leader's authority weakens.

Examples in context

A model AS paragraph on the debate might read: "The claim that Britain has acquired prime ministerial government captures a real long-term trend but overstates it. There is no doubt that power has flowed towards the centre: patronage gives the Prime Minister command over careers, the Number 10 machine and Cabinet committees have displaced much collective decision-making, and the media treat elections as a contest between leaders. Yet the office remains strikingly dependent. A Prime Minister governs only so long as the party and the Cabinet permit, and a series of leaders have been forced out by their own MPs rather than by the electorate. The judgement, therefore, is that prime ministerial dominance is the normal condition but a conditional one: it rests on authority that can drain away quickly, returning real power to the Cabinet and the party." This weighs concentration against dependence and reaches a verdict.
